The Facility, Part 8: Flare Knock-Out Drums and Vapour Recovery
The vapour-recovery unit trips and the low-pressure flare turns yellow. Explore why liquid must stay out of a flare, how knock-out drums are sized and emptied, and how liquid seals protect the header. Recovery compressors, ejectors, closed drains and cold-weather condensation complete the trail. Part 8 of 16 in The Facility. Corran Point, its characters, companies and story figures are fictional and illustrative.
